1227747 TBI BPW Calculator

[dave w]

I've seen several different BPW calculators, here is the one I wrote. The variables to enter are, Injector Flow in Lbs / Hr, Engine Displacement in Liters, and the number of cylinders usually 4, 6, 8.

That goes great with the Injector Size Calculater in another thread. I had used it to get fuel pressure needed for BB TBI injectors on a built engine. Tuned the engine. Just used your calculater and it was spot on to BPW that took me hours to get.

Thank you! :thumbsup:

The spread sheet is accurate within +/- %2, mostly because; rated injector flow vs. actual injector flow vs. ECM "programmed" injector flow is really like comparing apples vs. oranges vs. bananas.
